The chart below is an example of temperature in a healthy cycle. Remember all women are different so you could be perfectly healthy even if your chart differs a little. Typically a woman will have low temperatures in her pre-ovulatory phase. Once there are three high temperatures in a row it is confirmed that ovulation did occur. By charting your temperature you can determine when and if you are infertile and if protection needs to be used during intercourse. Temperature can tell you a lot about your fertility, but it is very important to track your cervical mucus as well. If you are serious about using the Fertility Awareness Method as birth control it is important that you fully understand how to chart your cycle in order to avoid an unplanned pregnancy.
